SPECIFICATION forming part of Letters Patent No. 319,427, dated June 2, 1885.

Application filed May 21,1884. (Model.) I

To all whom it may concern:

Be it known that I, WILLIAM J. SLYDER,a citizen of the United States of America, residing at Troy, in the county of Miami and State of Ohio, have invented certain new and usesashes, as described, a vertically-slidinglatch.

having lugs and recesses at its inner edge, whereby the same is adapted to hold the pawls in locked or unlocked position, and also to receive a key by means of which said latch may be slid vertically to unlock the pawls, and a removable key or lever for operating said looking pawls, all as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective of the rear face of my improved attachment with the pawls in looking position. Fig. 2 represents a similar view of the front face thereof. Fig.3 represents an end elevation thereof, partly in section, the full lines showing the position of the parts when looking both the upper and lower sashes, and the dotted lines showing the position of the parts when looking the upper and lower sashes, respectively. Fig. 4 represents a similar view showing the position of the parts when the pawls are retracted to permit of the free ver tical movement of both sashes.

It is the object of this invention to secure a simple and cheaplyconstructed device hav in g few parts and one easily appliedto the fram- 7 ing of a window, whereby either one or both of the vertically-sliding sashes may be securely held and locked either at any desired eleva-' tion orwhen entirely closed, or when one sash is entirely closed and the other partly or wholly opened, and also to secure the retraction of the locking devices, so as to permit of the free vertical movement of both sashes at the same moment, the several parts being adapted to be easily and quickly operated, so as to either leave the sashes free to move vertically or to lock either or both in any desired position without the possibility of interference with or any unauthorized change in the posi: tion of either sash' by parties on either the illside or outside of the window. V

A represents the frame or plate, within which the operative parts of the device are contained and move. This frame is of a shape and size to adapt it when inserted within a mortise or recess in the framing of a window to extend across the path of the respective sashes, as shown in the drawings. The outer edge of each sash is provided with either transverse notches or recesses or with a corrugated or notched bar, or equivalent device, with which the outwardly-extending lips or lugs of the pawls, to be presently described, may engage. The outer face of this plate or frame A is plain, as shown, with the exception that at one end there is at each corner'an inwardly-projecting bearing and guide-lug, B, within which re--.

ciprocate and rock the outwardly-projecting lugs or levers O, by which the pawls D are operated, and at or near the center a slotted guide, E, within which the key F is inserted when it is desired to retract the pawls.

Each lever or lug G is at its lower end pivotally connected with the outer end of an arm, G, (of which there are two, one for each pawl,) said arms being pivotally attached at their inner ends to the short shafts on the pawls, as hereinafter described, and rocking therewith as the levers G are depressed and released.

Near its upper end each lever O is provided with recesses, lugs, or notches I and J, by means of which said levers may be held in either the raised position they assume when the pawls are extended outward into operative position or in the depressed position-they assume when-the pawls are retracted. These recesses or notches may either both be formed in the lower edge of the lever at a suitable dis tance apart, or one of such lugs or notches 5 is limited by a shoulder, N, which, when said tended position. N Extendingoutwardlyfrom each rocklngarm G is a lug, K, which engages with the vertically-sliding pawl-locking plate or arm L, as will be presently described. This pawl-lock.- ing plate or arm is held with capability of free vertical movement within the key guide or centrally-projecting portion, E, the constanttendency of said plate L being to descend to its lowest position by the force of its own gravity. This plate or arm L is at each end provided with a lug or inwardly-extending projection, M, which, as said plate falls by gravity to its lowest position, pass and remain beneath said lugs K, and thereby prevent the depression of the levers G, and consequently of the pivotal arms G and the pawls D. The downward motion of the pawl-locking plate L plate drops down, impinges against the. lower lug- M. I

Centrally, or nearly so, of the pawl-locking plate L is a slot or recess, 0, of a shape corresponding with the wedge-shaped lower portion, P, of the key F. Upon said keybeing inserted within the-key-guide E, its lower end will enter the recess 0 in the plate L, and as said key is passed inward it will, by reason of its wedge shape, push said plate Lupward out of contact with the lugs K on the pivotal arms G. When so pushed up, the lower end of the locking-plate L passes up beyond the lower lug K and a slot or recess, 0, in the upper end of said plate L, and comes opposite to the upper lug K, by which means, when the levers O are depressed, said upper lug has free movement within said slot 0, and the lower lug has also a free movement beyond the lower end of said plate. In some instances, however, I dispense with this slot 0, and so construct and arrange the lugs K on the arms G and the lugs on the ends of the gravity-latch that the lugs Kwill pass clear of the outer ends of the lugs on the latch when said latch has dropped out of locking position and the arms G are de- T represents inturned lugs,whieh e2tend rearwardly from the frame A in opposite dir'ections. and embrace such rims. or enlargements for the purpose of holding said pawls in place within the frame and affording a rocking bearing therefor.

Extending inwardly from each pawl is an arm or shaft, U, which connects with the pivwith each other, so that when desired either the upper or the lower sash can be securely locked, while the other sash can be raised or lowered; or either or both sashes can be locked either partly or wholly closed. When it is desired to otalendsof the arms G, so that on the levers leave the sashes locked while either partly or entirely closed without the possibility of their position being changed or tampered with by parties inside the house or building, the key P is removed. Upon the removal of the key the plate L will by its own gravity drop down until the lugs M on the ends thereof come immediately beneath the lugs K on the rocking arms G, whereupon said arms G, and consequently the levers G and pawls D, are securely held from movement and the whole of the moving parts locked. By placing this attachmentwithin the side framing of the window it is out of the reach of parties on the outside, and by removing the key P the device cannot be operated by parties either outside or inside of the window. Consequently, even should a burglar cut away a portion of the glass with the'expectation of thereby being able to release the catch, he will not be able to unlock said catch. 7

This locking attachment cannot be operated from the outside by the insertion between the sashes or between the sashes and windowframe of av knife or other tool. It therefore affords a very secure and effective fastening at all times, especially as the keyP can be removed at any time after the sashes have been adjusted. v v v Although I have shown the gravity-latch as operated by a wedge-shaped key, it is evident that in lieu thereof an ordinary slot or opening may be formed in the side E of the frame, and a key ,of any ordinary construction passed therein into engagement with the latch so that upon turning such key partly around said latch may be slid along, such being a very evident modification and no departure from my invention, asherein set forth.

Having thus described my invention, what I claim -is 1. A sash-holder consisting of a suitable frame, A, latches or pawls having pivotal bearing therein and adapted to engage the respective sashes, levers or arms connected with said pawls and adapted to rock the same, a gravity-latch adapted to engage said pawloperating mechanism, and means, substantially as described, for retracting said gravitylatch, as and for the purpose set forth.

2. The combination, in a sash-lock, of a gravity-latch adapted to engage the sash-lockoperating mechanism and hold the same rigid, and having a slot or recess therein, a key adapted to fit the recess in said latch and force said latch upward. out of contact with the sash-lock mechanism, and a key-guide for guiding said key to and holding it in operative position, substantially as set forth.

3. The combination, with the pivotal pawls of rocking spring-arms connected or latches,

therewith and having outwardly-projecting lugs, levers adapted to depress said rocking arms, a gravity-latch having at each end a lug adapted to engage the lugs on the rocking arms and hold the same from movement, and means, substantially as described, for raising said latch out of operative position.

4. The combination, with the pivotal pawls or latches, of the frame A, having guideways for guiding the pawl-operating levers, and the pawl-operative levers adapted to engage said guideways for the purpose of retaining them and the parts connected therewith in position, substantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
